本論文研究之目的是發掘新的節能方法與技術，因地球資源已過度消耗，為了更有效地利用我們所剩不多的資源，而減少資源的浪費就成了目前最重要的課題。
本論文提出的節約能源理論是根據熱泵原理，將傳統飲水機導入熱泵系統應用，提高壓縮機使用效率。傳統飲水機在製造冰水時會將冷凝熱直接排入大氣中，未回收也未做其他利用。本論文將傳統飲水機加裝一個自製的熱水儲桶做為熱泵迴路，在熱水儲桶內裝水並讓高溫冷媒流過熱水儲桶表面，藉由熱交換原理將冷凝熱傳給熱水儲桶內的水，透過熱水儲桶收集製冰時所產生的熱，可以使熱水儲桶內的水溫上昇10℃，而這個熱值將可減少電熱器的電力使用量並縮短熱水加熱時間。
本論文重點在於如何將廢熱集中回收，實驗方法是將傳統飲水機加裝兩個可啟閉的閘閥。一個閘閥控制冷媒流入未回收的原管路，作為對照組；另外一個閘閥則是控制冷媒流入熱水儲桶的管路，作為改良組。利用水為介質並記錄水溫的變化以計算壓縮機效率與實際熱水回收熱量。
本論文結果證明傳統飲水機導入熱泵系統，具體地提高了壓縮機的效率約19.9%，若直接換算成熱水加熱的效率則提高了約13.6% 的電力。
本論文最大價值是可以利用熱泵原理作為傳統飲水機製造業之節能技術重要參考。

The goal of the present research is to discover the new energy conservation method and the technique, due to the earth resource has consumed excessively. In order to use the few remaining resources effectively, how to reduce the waste of resources has become the most important topic now-a-days.
The present thesis proposed the energy conservation theory based on the heat pump´s principle, imports the application of heat pump system into the traditional water dispenser to enhance the using efficiency of the compressor. The traditional water dispenser emits the condenser heat directly into the atmosphere while making the cool water; the condenser heat was not recovered neither collected for other usage. A heat preservation barrel has been made and installed into the traditional water dispenser to forms a circulator system of heat pump. Fill water into the internal of heat preservation barrel and let the high temperature reefrigerant flows through the surface of the barrel. Because of the heat exchange´s principle the condenser heat was transmitted to the water inside the barrel. Through the heat collected by the heat preservation barrel while making cool water, it can enhance the temperature of the water inside the barrel up to 10℃, and this heat value can reduce the energy consumption of the electric heater at the same time reduce the water heating-up time.
The key point of the experiment is how to concentrate and collect the waste heat. The experimental method is installed two open-shut gate valves into the traditional water dispenser. A gate valve controls the refregerant flow into the original un-recovered pipeline, as the comparison group; the other gate valve controls the Freon to flow into the pipeline of heat preservation barrel, as the improved group. Using the water as the medium and record the changes of water temperature, in order to calculate the compressor´s efficiency and the actual hot value recovered by the hot water.
The result of this research proved that the traditional water dispenser with heat pump system imported, the compressor´s efficiency has been enhanced about 19.9% concretely. If convert it into the heating efficiency of hot water, it enhanced the power about 13.6%.
The greatest value of this thesis is the usage of heat pump´s principal as an important energy conservation technique for the traditional water dispenser manufacturers.
